#000 Megasuchus (ZenithGreymon)

Note: This is both an original creation AND a fan Digimon due to how it's in-universe backstory works. Long story as to how that works.

Yes, I am fully aware this thing resembles Greymon; it's a plot point as to how this thing even exists at all in the story it appears in. Specifically, it first existed as a homebrew Zauridon in an original story, then later exists approximately 15 years later in my current Digimon fanfic as a result of the same hacker growing up to implement the creature into Digimon, where it's called ZenithGreymon.

Roles:

In a Digimon World inspired fanfic I'm working on, there's currently a savage Imperialdramon on the loose in addition to Analogman's normal threat. At some point, the protagonist obtains a MegaSeadramon sometime after unlocking the ability to digivolve his Digimon to Mega Level. Sometime during this, the original planned final form was MetalSeadramon, but instead of that, MegaSeadramon becomes ZenithGreymon through unknown methods. When talking to Jijimon about this new form, Jijimon and Centarumon examine ZenithGreymon to discover the form that he has now is the result of an unknown glitch, and that they have no idea who is responsible for it; they've double checked everything related to Analogman and the Back Dimension, and no results are found as to how ZenithGreymon could be related to them.

In addition to becoming the partner Digimon's current form for this arc, in this form only he has an almost entirely different personality. Every time he wins a battle, he states Solomon's trademark "Still the best 1973" from the NES Godzilla Creepypasta, except instead of 1973, he says 1999 instead for reasons unknown. In behind the scenes notes, ZenithGreymon was created by the very same hacker who had created Megasuchus approximately 15 years prior to this story.
